While I am absolutely in favor of the immediate development of a transitional plan for migration to a unified North American jurisdiction for the Eastern Orthodox Christian Church, some type of accommodations are going to have to be established for maintenance of cultural variances and existing practices. Frankly, Saint Tikon's proposal for "some type of autonomy," which he had proposed to the Russian Holy Synod at the beginning of the 20th Century, should be published in English. It may very well serve as a basis for a realistic plan for unified administration.
A single bishop for a regional diocese will tend to impose his own perspective and ecclesiology. There will be customs and practices which a bishop will not wish to accept, such as the requirements for preparation for the reception of Holy Communion. There are many more variances that exit, especially in today's America, that should not be unilaterally changed, at once. The initial American Orthodox jurisdictional unity must be able to accommodate the existing variances. Parish lenten observance practices, days when the Sacrament of Holy Matrimony can be performed, and for that matter, the Typicon (Jerusalem & Constantinople) itself, will have to accommodate existing variances. It is a massive project, but rather than simply ignoring the problem, SCOBA, with the participation of other bishops, priests, deacons and laity, should be working toward preparation of the ultimate plan for a unified jurisdiction for North America, now. Property ownership and its location, i.e. where offices of the dioceses and camps will be located, are other major aspects of what must be determined prior to the conversion to a unified jurisdiction.
Utilizing respectful, yet firm and sincere diplomacy with the Eastern Patriarchates, perhaps with the strategy Metropolitan Phillip employed with the Patriarchate of Antioch which resulted in autonomy for his archdiocese; such planning could realistically be accomplished, tansitionally, without changes in existing church statutes, constitutions or charters and regulations.
